Homework Help: Find Z and A for nuclear reaction

  1. Aug 7, 2008 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    ?

    3. The attempt at a solution
    In our previous homework, this is the only problem I got wrong, I feel the book does a very poor job at explaining over this subject. I went to physics help room but because its summer the guy was only there for lower level physics classes and said could not help me. I have a quiz tomorrow and want to clear up my misunderstanding.
    My guess would be that Z = 5 and A = 10 and if that is even right how does one tell if the energy is absorbed or liberated?
    Thank you
